Values applicable in properly drained, sound soils with a minimum 1500 psf bearing capacity. See IRC <br /> Table R401.4.1 for complete bearing soils listing and Table notes. <br /> 2. For simple structures only. No asymmetrical, rotational, overturning, or dynamic loads. For additional <br /> information, see the full Diamond Pier Installation Manual. <br /> 3. All capacities use four pins of the specified length per foundation. Length includes that portion <br /> embedded within the foundation head. <br /> 4. DP-50 uses defined in paragraph 2.0 of ESR-1895 and per blue-bordered box above are limited to <br /> residential decks, covered decks, stairways, and walkways. For DP-50 uses beyond these types of <br /> projects, and for DP-75 applications, refer to Cross Pin Group Test Report(EEI Report No. 07-020-8). <br /> See Note 1 for applicable soils. <br /> 5. 50" Pins are recommended for use with the DP-50 where uplift and/or lateral loads may govern. The <br /> DP-50 comes with a 1/2" diameter embedded galvanized anchor bolt. The DP-75 comes with a 5/8" <br /> diameter embedded galvanized anchor bolt. <br /> 6. The Diamond Pier system is a shallow bearing technology that does not require"refusal" or"friction" <br /> resistance, or the professional installation monitoring or special inspection typically associated with <br /> conventional vertical or battered piling. <br /> 7. This load chart is intended for applications supported by columns, posts, and beams loaded up to but <br /> not exceeding the stated capacities. For applications where the load requirements exceed the <br /> capacities defined in this chart, a site-specific capacity review is required. Project soils data and <br /> structural loading information must be provided.
